4. The method of claim 3 , wherein the one or more rigid rings are stitched onto the 2D structure and wherein the attachment structures are stitch holes or grooves.

5. The method of claim 1 , wherein removing the mold from the 3D endoprosthesis comprises: applying pressure to the mold, wherein the mold is a crushable mold fracturing into discrete pieces upon application of pressure.

6. The method of claim 1 , further comprising: designing a 3D model of an endoprosthesis based on the patient's corrected vessel anatomy or part thereof.

7. The method of claim 1 , wherein the endoprosthesis is a personalized aortic endoprosthesis which fits at least partially with the ascending aorta, the aortic arch and/or the thoracic aorta.

8. The method of claim 1 , further comprising: manufacturing the mold by additive manufacturing.

9. A non-transitory, computer-readable medium comprising computer-executable instructions that, when executed by a processor in a computing device, cause the computing device to perform a method of manufacturing a luminal endoprosthesis fitting at least part of a patient's lumen anatomy, the method comprising: designing a 3D model of a vascular endoprosthesis, based on a 3D image of the patient's anatomy or part thereof; unfolding the 3D model to a 2D pattern of the endoprosthesis; manufacturing a 2D endoprosthesis structure from the 2D pattern; providing a mold for the vascular endoprosthesis; assembling the 2D endoprosthesis structure around the mold so as to obtain a 3D endoprosthesis; and removing the mold from the 3D endoprosthesis.

10. The non-transitory, computer-readable medium of claim 9 , wherein assembling the 2D endoprosthesis structure around the mold so as to obtain a 3D endoprosthesis comprises attaching one or more rigid rings or crowns onto the 2D structure.

11. The non-transitory, computer-readable medium of claim 10 , wherein the 3D model of the endoprosthesis comprises grooves conform to the one or more rigid rings or crowns and/or attachment structures.

12. The non-transitory, computer-readable medium of claim 11 , wherein the one or more rigid rings are stitched onto the 2D structure and wherein the attachment structures are stitch holes or grooves.

13. The non-transitory, computer-readable medium of claim 9 , wherein removing the mold from the 3D endoprosthesis comprises: applying pressure to the mold, wherein the mold is a crushable mold fracturing into discrete pieces upon application of pressure.

14. The non-transitory, computer-readable medium of claim 9 , wherein the method further comprises: designing a 3D model of an endoprosthesis based on the patient's corrected vessel anatomy or part thereof.

15. The non-transitory, computer-readable medium of claim 9 , wherein the endoprosthesis is a personalized aortic endoprosthesis which fits at least partially with the ascending aorta, the aortic arch and/or the thoracic aorta.

16. The non-transitory, computer-readable medium of claim 9 , wherein the method further comprises: manufacturing the mold by additive manufacturing.

17. The method of claim 1 , wherein removing the mold from the 3D endoprosthesis comprises: removing pressure from the mold, wherein the mold is a flexible mold.

18. The non-transitory, computer-readable medium of claim 9 , wherein removing the mold from the 3D endoprosthesis comprises: removing pressure from the mold, wherein the mold is a flexible mold.

19. The method of claim 1 , wherein unfolding the 3D model to a 2D pattern of the endoprosthesis comprises at least one of unwrapping, unrolling, or U-V parameterized unfolding of a shell of the 3D model onto a 2D surface.

20. The non-transitory, computer-readable medium of claim 9 , wherein unfolding the 3D model to a 2D pattern of the endoprosthesis comprises at least one of unwrapping, unrolling, or U-V parameterized unfolding of a shell of the 3D model onto a 2D surface.

21. The method of claim 1 , wherein the 2D pattern of the endoprosthesis comprises a plurality of parts, and wherein assembling the 2D endoprosthesis structure around the mold comprises assembling the plurality of parts.
